Sorry to say, but I was laughing when reading your "reply". Every country got different laws. So you would find in different countries law abiding, mentally sound individuals. The standards/laws are different. Standards we are used to accept, but not accept by other countries or religions. Then, who sets these standards and who will decide if you are mentally sound?
Think again and you will see that you're in a dead end street.
(Just a reminder: remember what happens with weapons in US High Schools or Universities...without those things many young innocent young people would not have murdered)🙏
